Title: Multicolour raster printed product and method and device for its manufacture
Inventor: PFISTER JOSEF
IPC: B41M1/18
Filed: 1986-08-20
Abstract: In order reliably to obtain a subtractive colour tone mixture with a given colour tone by printing the individual colour dots (6, 9) on top of one another, even in the case of tolerance errors (so-called register errors), at least one colour dot (6) is distributed within its raster zone (3) whilst maintaining the saturation within said raster zone (3) so that the individual colour spots (6') thus produced each have a different saturation on the multicolour raster printed product. Alternatively or additionally, a plurality of raster dots of the same colour can also be provided within one raster zone (3) so that the probability of coverage is increased. To produce such a multicolour raster printed product and to carry out the method, a known device is expediently provided additionally with a cylinder for applying a solvent. <IMAGE>

Title: Apparatus for mixing fine-grained material, in particular cement, lime, ash and other mineral substances
Inventor: DELFS HANS-JUERGEN DIPL ING
IPC: B01F7/24
Filed: 1986-08-29
Abstract: The apparatus for mixing fine-grained material, in particular cement, lime, ash and other mineral substances, has a mixing container, in which at least two mixing screws 8, 12 are arranged in closed tubes 7, 11. These mixing screws convey the fine-grained material to be mixed from the bottom upwards at differing rates, so that the upward speed for the material differs. The downward speed of the material introduced at the top is equal, so that fast and intimate mixing is ensured. There are in practice different paths for the upward and downward flows of the material to be mixed, the upward speed in the tubes differing. If continuous mixing operation is desired, an additional delivery screw which leads out of the mixing container can be provided in a closed tube. <IMAGE>
Patent DE-3644707-A1 (DE)
Title: Drill hammer
Inventor: BAUMANN OTTO
IPC: B23B45/16
Filed: 1986-12-30
Abstract: To improve the free-striking of tools in drill hammers with jaw chuck, the snap (4, 32) is surrounded by a separate percussion sleeve (22). During the free-striking, the energy of the percussion member (3) alternately hits the tool shank (19) via the snap (4) and the drill-chuck body (12) via the percussion sleeve (22). Reliable free-striking, within a short time, of parallel-shank drill bits of any diameter in drill chucks with carbide-tipped chuck jaws (17) is thus possible, so that the drill bit is axially freely movable. <IMAGE>
Patent DE-3703786-A1 (DE)
Title: Connecting device with a quick-fastening screw
Inventor: ELSNER HANS
IPC: F16B5/10
Filed: 1987-02-07
Abstract: On using quick-fastening screws, for example, for connecting a housing cover to a housing bottom part, the quick-fastening screw projects through a bore in the housing bottom part and engages into a spring wire arranged on the rear side, with the result that the interior of the housing is in connection, via the bore of the quick-fastening screw, with the outside, or the quick-fastening screw engages into a helical spring in a sleeve which is closed on one side, this resulting in a long structural shape. In the case of the connecting device according to the invention, the quick-fastening screw engages only into a blind bore of the housing bottom part, and the spring wire is fastened, preferably in a groove, on that surface of the housing bottom part which is directed towards the lid. Consequently, a seal between the two housing parts is not impaired by the connecting device. <IMAGE>

Patent DE-3718287-A1 (DE)
Title: Netting or sheeting enclosure
Inventor: HARTENBACH HERBERT
IPC: A01K61/60
Filed: 1987-05-30
Abstract: The netting or sheeting enclosure is intended for use in standing and/or flowing water. It comprises a netting (30) or a sheeting and a plurality of floats (10) which hold the netting at least partially on the water surface. The floats (10) contain a metal platform (16) on which a retaining device (22) for the netting (30) can be fastened. The platform is enclosed by an air-filled annular chamber (20) which is sealed with respect to the penetration of water and is delimited by a rubber casing which rests in a sealing manner on the border of the platform.

Patent DE-3720236-A1 (DE)
Title: Drive system, particularly for motor vehicles
Inventor: MEHNERT GUENTER
IPC: F02B33/44
Filed: 1987-06-12
Abstract: Drive system, particularly for motor vehicles, inter alia for those with a combustion engine, having at least one epicyclic gear set and a device for the mechanical supercharging of the engine comprising at least one compressor with a displacer action, an upstream vacuum chamber and a downstream plenum chamber and return flow passages and throttle valves. Power transmission, rotational speed variation and engine supercharging are controlled continuously as the engine operates by throttling the air flow, a steady vacuum in the intake-side vacuum chamber enabling autonomous cooling of the system under load while the compressor serves as a reaction member and, in this capacity, exerts positive control over the output speed and the output torque. To increase the torque, a reduction component of the epicyclic gear set is supported radially on the central shaft of the gear set via planet wheels and at least one compressor, the compressor being arranged so as to be rotatable about this central shaft. The compressor reaction is routed in such a way that the reduction component and a direct driving component are superimposed and an increased output torque is obtained, this output torque varying continuously (as the reciprocal of the output speed) when the transmission ratio is changed. The range of adjustment stretches from idle to a transmission ratio of 1:1.
Patent DE-3722144-A1 (DE)
Title: Vibration absorber for rotating shafts
Inventor: BARSCH HANS-PETER DR
IPC: F16F15/14
Filed: 1987-07-04
Abstract: In vibration absorbers for passenger-vehicle propeller shafts with a relatively high rotational speed, rolling elements are used to prevent the radial drift of the flywheel ring. In the new absorber, the intention is to achieve reliable guidance of the rolling elements while at the same time increasing the damping effect. To achieve this object, the rolling tracks of the rubber layers (11, 12) are provided with radial projections (13, 13') and the rolling elements (8) are provided with depressions (15) and these mesh as they roll upon one another. The tooth-like guidance aids make the absorber particularly suitable for passenger-vehicle propeller shafts with a high rotational speed. <IMAGE>

Title: Device for unlocking and locking doors, in particular motor vehicle doors
Inventor: EISELE ALBERT DIPL ING
IPC: E05B65/38
Filed: 1988-02-09
Abstract: In a device for unlocking and locking motor vehicle doors, in the case of which device lock actuating elements are arranged in each case on the individual doors, it is proposed to arrange a selectively functioning coupling device in such a manner that, in the event of locking the vehicle door centrally from outside with a key, opening by actuation of the door button mechanisms is ruled out; if, on the other hand, the central locking position is achieved by pressing-in of door button mechanisms and driving, resulting from this pressing-in, of a first lifting rod (B) which moves electrical control switches for the pump actuation, this results in such a (temporary) coupling with the first lifting rod that the transfer into the unlocked state is also possible by means of door button actuation. <IMAGE>

Abstract: The object is to provide a circuit arrangement which produces voltages with different polarity in a simple manner. The voltages are intended in particular to be floating voltages and, for example, to be usable for high-level transmission of telex signals. In order to produce the voltages, a transformer (Ü) is provided which is driven on the primary side by push-pull signals (S1, S2) which are mutually inverted and which have a non-equal mark-to-space ratio. The mark-to-space ratio is fixed as a function of the instantaneous value of a control signal (S). On the secondary side, a rectifier circuit having two controlled switches (T3, T4) is provided, to which switches the voltages (+/-U) are supplied and with which diodes (D1, D2) are connected in parallel, the forward direction of the diodes (D1, D2) being opposite to that of the corresponding controlled switches (T3, T4). The circuit arrangement can be used wherever floating voltages with different polarity are switched alternately. <IMAGE>
